Net change in the stock market represents the difference between a stock’s current trading price and its closing price from the previous trading day. It quickly indicates whether the stock price has increased or decreased during the session, helping investors and traders gauge market sentiment and price momentum.
The formula to calculate net change is:
Net Change = Current Price – Previous Closing Price
For example, if a stock’s previous close was ₹320 and its current price is ₹325, the net change is +₹5, indicating a price rise. Conversely, if it falls to ₹315, the net change is -₹5, showing a decrease.
Reading Stock Quotes
Stock quotes typically show key data like the last traded price, net change, percentage change, volume of shares traded, and dividend yield. The net change figure often appears next to the price, with green color indicating a gain and red indicating a loss, providing an immediate visual cue of price movement.
For instance:
- Company: ABC Ltd
- Last Trade: ₹200
- Net Change: +₹3 (price went up)
- % Change: +1.52%
- Volume: 1,00,000 shares
- Dividend Yield: 1.5%
This helps investors quickly decide whether to buy or sell based on the stock’s price movement and market activity.

Significance in Market Analysis
Net change helps measure how efficiently the market processes new information. Large net changes often follow major news events, earnings reports, or economic shifts, reflecting investor reaction and sentiment. It is also used in technical analysis to confirm price trends, where a strong net change combined with high volume often signals a robust movement.
Technical Analysis Use: Point-and-Figure Charts
Technical analysts use net change in charts like Point-and-Figure (P&F) charts that focus solely on price movements. These charts filter out minor fluctuations and highlight significant trends and reversals, aiding investors in identifying support, resistance, and long-term buying or selling pressures.
Conclusion
Net change is a fundamental yet powerful tool for monitoring stock price movement. By showing the price difference from the previous close, it gives investors immediate insights into market direction and strength. When combined with other data such as trading volume and market news, it becomes invaluable for making timely trading decisions and understanding market dynamics.
